Description

Technical Field

[0001] This utility model relates to the field of silica sand beneficiation technology, specifically to a silica sand water screening machine. Background Technology

[0002] Sand washing removes impurities from sand and gravel using physical or chemical methods to meet industrial or construction standards. The process typically involves dump trucks feeding raw sand and gravel into a conveying system. Multiple conveyor belts then feed the sand into a discharge device, which, in addition to a discharge hopper, sprays a large amount of water for initial cleaning. The silica sand is then fed into a silica sand wet screening machine for grading and sieving. After screening, the sand particles enter a wheel-type sand washing machine for further washing. The impeller agitates the water flow, removing surface mud and impurities. A fine sand recovery machine is also included to reduce sand loss. However, because the silica sand particles fed into the wet screening machine contain a large amount of moisture, the screen openings in existing silica sand wet screening machines are extremely prone to clogging. Furthermore, the sand is not cleaned during the screening process, leading to incomplete screening. Utility Model Content

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figure 1 and Figure 2 The diagram shows the structure of the silica sand water screening machine of this utility model. The silica sand water screening machine of this utility model includes a base, a drum screen, a feeding cylinder, and a driving device. The base has two front baffles 11 and two side baffles 12. The two front baffles 11 and the two side baffles 12 have a rectangular discharge hole 13 in the middle. In addition, the feeding cylinder has two feeding plates 21, two fixed crossbeams 22, and several support frames 23. The fixed crossbeams 22 are respectively fixed to the upper outer side of the feeding plates 21. The upper end of the support frame 23 is fixedly connected to the fixed crossbeams 22, and the lower end is vertically set on the upper end surface of the side baffles 12. Thus, the two feeding plates 21 can be fixed on the base by means of the fixed crossbeams 22 and the support frames 23. The lower end of the two feeding plates 21 forms a feeding port 24, which is located in the rectangular discharge hole 13. The drum screen rotates on the base by the driving device. The specific driving method is as follows.

[0019] In this utility model of a silica sand water screening machine, the drum screen is provided with a screen 41, two rolling rings 42, several support shafts 43 and several positioning rings 44. The screen 41 has a cylindrical structure. The two rolling rings 42 are located at both ends of the screen 41, and the two ends of the support shafts 43 are fixed on the inner side of their corresponding rolling rings 42. The screen 41 is fixedly surrounded on the outside of the support shafts 43, and the positioning rings 44 are sleeved on the outer wall of the screen 41. In addition, the two ends of the drum screen and located inside the rolling rings 42 are respectively provided with a feed inlet 45 and a debris removal inlet 46. A feeding device (not shown in the figure) is fixed inside the feed inlet 45. The feeding device is a structure for feeding silica sand particles into the drum screen. In the prior art, the feeding device is provided with a hopper, and a water pipe is installed in the hopper to wash the silica sand raw material with water before feeding it into the drum screen.

[0020] Furthermore, the outer end of the feed inlet 45 of this invention is provided with a first rotating gear 51, and the outer end of the waste outlet 46 is provided with a second rotating gear 52. The driving device includes a driver 61, a reducer, a coupling, a rotating shaft 62, and a driving gear 63. The reducer and coupling are not shown in the figure, and their structure is existing publicly available technology, so they will not be described in detail. The output shaft of the driver 61 of this invention is connected to the reducer through the coupling. The output shaft of the reducer is rotatably connected to one end of the rotating shaft 62, thereby the driver 61 provides rotational driving force to the rotating shaft 62. The reducer can adjust its speed appropriately. In addition, the rotating shaft 62 is sleeved on the driving gear 63, and the driving gear 63 meshes with the first rotating gear 51. In other preferred embodiments, there are two drivers 61, two rotating shafts 62, two drive gears 63, and two driven gears 65. The driven gears 65 mesh with the second rotating gear 52. The driven gears 65 are located at the end of the rotating shaft 62 away from the drivers 61, and the driven gears 65 are rotatably fixed to the upper surface of the front baffle 11 by the positioning structure 64.

[0021] Therefore, after starting the driver 61, the rotating shaft 62 rotates at an appropriate speed, which in turn drives the drive gear 63 to rotate. Simultaneously, the first rotating gear 51 rotates. Since the first rotating gear 51 is fixedly connected to the rolling ring 42, the rolling ring 42, the screen 41, and the support shaft 43 rotate simultaneously during the rotation of the first rotating gear 51, thereby achieving the sieving of silica sand within the screen 41. In other embodiments, the screen 41 can be segmented to differentiate screen hole sizes, thereby achieving the purpose of classifying and screening silica sand particles to obtain silica sand bodies of different particle sizes.

[0022] In other embodiments, this utility model also includes a rotating plate 71, a shaft positioning member 72, and a mounting frame 73. The outer end of the mounting frame 73 is fixed to the support frame 23. In other embodiments, the outer end of the mounting frame 73 can be directly fixed to the side baffle 12. The rotating plate 71 is fixedly sleeved on the rotating shaft 62. There are two shaft positioning members 72, which are movably sleeved on the rotating shaft 62 and located on both sides of the rotating plate 71. The feeding plate 21 has a notch at a position corresponding to the rotating plate 71, and the rotating plate 71 can rotate within the notch. The rotating plate 71 cooperates with the positioning ring 44. Specifically, the outer peripheral wall of the positioning ring 44 can be provided with a groove, and the outer edge of the rotating plate 71 is located in the groove. When the screen 41 rotates under the drive of the driving device, the rotating shaft 62 will rotate at the same time, and the outer edge of the rotating plate 71 will rotate in cooperation with the positioning ring 44, thereby limiting the position of the screen 41.

[0023] Please continue reading. Figure 1 As shown, the upper end of any fixed crossbeam 22 of the silica sand water screening machine of this utility model is provided with several mounting seats 31. Water pipes 32 are mounted on the mounting seats 31 (a partial structural schematic diagram is shown in the figure). The water pipes 32 are movably fixed to the mounting seats 31 by clamps, and several high-pressure nozzles 33 are distributed on the water pipes 32. The silica sand water screening machine of this utility model has water pipes 32, and high-pressure nozzles 33 are installed on the water pipes 32. The high-pressure nozzles 33 further clean the silica sand inside the screen 41, and at the same time, the high-pressure nozzles 33 can also rinse the screen holes on the screen 41 to prevent them from clogging.

[0024] Please see Figure 2 As shown, the upper end of another fixed crossbeam 22 of this utility model is provided with a cleaning structure. The cleaning structure is used to prevent clogging inside the screen holes of the drum screen. Specifically, the cleaning structure includes a connecting plate 81, an adjustable rotating plate 82, a support plate 83, and a brush body 84 located on the support plate 83. The connecting plate 81 is fixed to the upper end surface of its corresponding fixed crossbeam 22. One end of the adjustable rotating plate 82 is rotatably connected to the upper end of the connecting plate 81 by bolts, and the other end is fixedly connected to the back of the support plate 83. The cleaning structure provided in the silica sand water screening machine of this utility model can further thoroughly clean the clogged screen holes and improve screening efficiency.
